SOME REMARKS CONCERNING RECENT WORK ON ROTATING TURBULENCE

Some aspects of a recent paper on rotating turbulence by Canuto and Du bovikov [Phys. Fluids 9, 2132 (1997)] are examined from historical and scientific perspectives. Their claim to have discovered a new energy spectrum scaling law for rotating turbulence is examined in light of p revious publications on this subject. We answer an objection raised to the consistency of this spectral scaling law with the Bardina-type di ssipation rate transport equation derived from this law by two of the authors [Phys. Fluids 8, 3172 (1996)]. Finally, some difficulties with the alternative model for the dissipation rate transport equation pro posed by Canuto and Dubovikov are described in both the weak and stron g rotation limits.
